Why is it important to label diagrams before answering questions?

• To impress the examiner

• To make the diagram look neat

• To avoid misidentifying components and making mistakes

• To save time during the exam

What should you do if you cannot label all parts of a diagram immediately?

• Skip the question

Which part of the ear absorbs excess pressure waves from the inner ear?

• Round window

• Cochlea

• Oval window

• Semicircular canals

What is the function of the medulla oblongata?

• Regulating basic functions like heartbeat and breathing

• Processing visual information

• Maintaining balance

• Controlling voluntary movements

What is the role of the organ of Corti?

• To maintain balance

• To absorb excess pressure waves

• To detect sound vibrations

• To regulate heart rate

Which part of the brain is responsible for basic life functions?

• Cerebrum

• Cerebellum

• Thalamus

• Medulla oblongata

How does the cerebellum respond to impulses from the semicircular canals?

• By regulating heart rate

• By controlling speech

• By maintaining balance and coordination

• By processing auditory information

What happens when the oval window hardens with age?

• It enhances balance

• It causes hearing loss due to reduced sound wave transmission

• It increases pressure in the inner ear

• It improves hearing

What is the consequence of the oval window not vibrating freely?

• Enhanced balance

• Improved sound clarity

• Increased ear pressure

• Hearing loss due to lack of pressure wave formation
